QCM Biosensors for pathogen detection in water and food : review of published literature
Introduction: This article is the result of the review “QCM Biosensors for the Detection of Pathogens in Water and Food: A Review,” conducted during the years 2023 and 2024 at the Universidad Distrital Francisco José de Caldas.
Problem: The fast evolution of pathogen detection through biosensors requires a continuous synthesis of literature to provide an integral comprehension of the state of the art to new researchers.
Objective: Perform bibliography research about QCM Biosensors used for pathogen detection in food and water covering a period from 2018 to 2023.
Methodology: The research includes three phases: An explanation of the principles of QCM biosensors, their use in water and food pathogen detection, and their use in industry, with an emphasis on water quality.
Result: QCM biosensors are solid, measure mass changes at the micro and nanometric scales, and are widely used in the food industry due to their accuracy and ease of use.
Conclusion: The review highlights the effectiveness of QCM biosensors when detecting different food contaminants and pathogens. It underlines the practical research necessity and importance of updating review papers to orientate future investigations in this specific area.
Originality: The originality of this review lies in its detailed approach to QCM biosensor use in food pathogen detection.
Limitations: The constant evolution of the field of pathogen detection in addition to the diversity of QCM biosensors and the wide range of pathogens studied may make it difficult to generalize certain findings.
